IMPROVEMENT I FUNNELS.

The Schedule referred to in these' Letters Patent and making pan of thesame.

To all whom it may concern Y Be it known that I, WILLIAM LEDMUN, ofBridgeville, in the county of Sussex, and State of Delaware,haveinveuted a new and useful Improvement in` Fuinnels; and l do herebydeclare the following to he a tull and-correct description of the same,sufficient toenable others skilled in the class to which my inventionapperta-ins to fully understand and construct the same, reference'beinghad tothe accompanying drawings which make part of thisspecification,'and

in which f o l Figure 1is a vertical section` of my improved fun- Figure2 is a perspective view, showing the attachment of the lower to theupper part; and

Figure 3-is a sectional bottom view of the upper ike letters ofreferenceindicate like parts in the severaligures. y l

The nature of my invention consists, first, in con-` structing a funnelin two parts, the tunnel proper and the spout, which are easily attachedto each other or detached from each other for the purpose ofcleansing;secondly,-i uthen1eans-of shutting oli" the ow of liquids, orletting the same on. A

A, in the drawings, represents the funnel proper,

. provided near its lowerend Iwith a straight vertical rim, B. Y r u 'lothe lower narrow end of the funnel A is secured a short metal blockorpiece, O, extending outwardly to one side. Y u

On this extending part is as to cover the, opening ofthe funnelcompletely, and prevent the discharge oi' fluids from the same when thelever is in position, as shown in dotted lined in' 3, but when inposition as shown in black lines,

saine figure, the lever 1s clear of the opening f the u funnel, andallows 4a free discharge of llui'ds from'the when the lever has closedthe opening of the funnel,

the pin c catching in notch d, prevents the lever from moving further inthat direction, and when the lever is moved free from the opening,othenotch d' hears against pin c with a like result.

The spout of the funnel is formed in a separate piece, E, having astraight vertical rim, F, titting snugly over rim B of the funnel.

`1n this rim F is forme-d an L- shaped slot, G, into which fits andslides a pin or projection, y, which forms one of the means of securing.

On the inside of rim B of the funnel, isv secured a pivoted alevel-,11),the inner shorter part of which is ot' a rounded shape, so

` bent spring, H, provided at its free end with a thumbpiece, I, whichpasses through the rim, as already shown in lig. 3. y

On the spring near its free end is formed a tongue, J, which passesthrough rim B and through rim F, and at a point opposite or nearlylopposite to the slot G. By pressingon the thumb-piece I, the tongue J ispressed inwardly vand out of the corresponding opening in rim F. Thisforms the other 'of the means of The rim F has a. part of itscircumference exserted, as shown in iig. 2,'

seeming the spout to the funnel.

to allow for the play of lever D, the lower edge ofthe ,rim B and theupper edge of the exserted part form'V ing a sort of slot for the level'to move in.

I provide the inside of the funnel A with projecting points, c, toineasure certain quantities by, the projecting points being easier seenand kept in sight than lines or other marks engraved into the surface ofthe funnel.

The operation of my improved funnel is a's 'ollowsrl lhe parts all beingconnected, as in fig. 1, the spout of the funnel is placed iu or overthe vessel to be filled, and the lever D moved so as toV close theopening of the funnel.,y rlhe liquid is then allowed to run from thecaskor other vessel into the funnel, 2until the de` sired quant-ity, asindicated by the point a., has :been reached, when, on moving lever I)so as'to free the opening of the funnel, the measured liquid is allowedto flow through spout E into the vessel to he iilled. Should it becomedesirable to clean the opening of the funnel and the inner part of thelever, the spout E is removed from the funnel by pressing thethumb-piece v I, and thus releasing rim F from tongue J and giving spoutE a short rot-ary movement around rim B, so as to bring projection gdirectly under the vertical part of the slot G, when, by moving spout Evertically from rim B, it will at once become detached.

The great advantage of my improved funnel is that it is formed in twopart-s, by means of which it can at any moment b e `cleansed withouttrouble, especially where one funnel has to serve in measuring outdili'erent liquids. Its construction is simple and its manufactureinexpensive.

Having thus described my invention, v

What I claim as new, and desire to secure by Letters Patent, is i 1. Alfunnel constructed in two parts, A and E, substantially as and for thepurposes set forth.

'2. In a movable funnel, the lever D,`when arranged between the funnelvA and spout E, substantially as and `for the purposes described.
